Log Message:
Simplify example of cv_timedwaitbt.
It is simpler if there is only one place we check the condition.
That said, there are cases where the caller needs to re-check before
choosing to fail (e.g., futex_wait in kern/sys_futex.c, which must
verify the condition before taking destructive steps to abort the
wait). But it's not clear that that's the norm.
